Application Madonna 1,1917. Serial No.17 2,195. I i

To allwhom it mag concern:

Beit known that I', EDWARD J. MALLEN, a citizen of the United States, and aresident of the city of New York, borough of Bronx,

in the county of Bronx and State of New York, have invented a new and Improved Air-Register, of which the followingis a full, clear, andexact description.

-My invention relates to regi air heating systems, and has reterence'more particularly toa register having aplurality of relatively-movable vanes, the relative movement of which vanes may be controlled.

An object of the invention is to provide a simple and inexpensive register of the class 7 described in which the adjacent vanes move in opposite directions.

A further object of the invention is to provide-a register in which the movement of the vanes from the initial or closed position may be regulated to'obtain the desired speed or velocity of air.

\Vith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters ofreference indicate corresponding parts in all the views.

Figure 1 is a plan view of a. register embodying my invention, certain part of the register .front being broken out to show the details of construction;

Fig. 2 is a cross section on line 22, Fig. 1;

Fig. 3 is a section on line 3-3, Fig. 4 showing the operating mechanism for the vanes; and

Fig. 5 is a fragmentary cross section through the register showing the vanes open and the stop mechanism set to limit the movement of the said vanes from their initial position.

Referring to the drawings, '6 is the register housing which has an apertured front 7 One side of the housing is recessed inwardly to form an inward pro ection 8 near the rear of the housing. The recessed part accommodates a pair of facing racks 9 each having toothed sections 10 spaced from one another. The number of the sections on each of the racks depends on the number of vanes 11 in the register housing. Each of the vanes sters for hotis provided with trunnions 12, one bearing in the raisedportionS and the other in the opposite side. The trunnion bearing in theraised portio'nfS projects therethrough' to receive-a p1I'11ony-13 whlchengages a section 10 of the rack.

The two racksare secured rigidly to an arm lf kprojecting througha slot in the side of-the recess s, as well as through the front 7 of the register housing. By moving the arm in the slots the racks are caused to slide in the recessed partand, therefore, the pin.

ions-are caused to rotate; in consequence, the

vanes are also revolved or oscillated. It will be noted thatthe 'adjacent pinions mesh with the rack sectionson the opposite racks; in

consequence,, the adjacent vanespwill IGVOlXB in opposite directions. Due to this the vanes will present diverging andconverging passages symmetrical to a plane normal with the plane of the register (see Fig. 5). The aperture or passage formed by the adjacent vanes may be varied or adjusted by means of a slide 15 supported on a lug 16 provided in proximity of the arm 14. The lug 16 is so positioned that when the arm let is moved against it, the vanes 11 are in planes normal to the plane of the register. A similar lug 17 is provided on the other side of the arm 14, and it is so located that the arm 1& abuts against it when the vanes are in a plane parallel to the plane of the register, or, in other words, when the register is closed or is in its initial position. By moving the slide 16 to Ward the arm 14 the size or width of open ing to be formed by the adjacent vanes may be varied, a set screw 18 being provided for locking the slide 15 to the lug 16. In cases where the vanes are to be prevented from closing, a similar slide 19 may be provided on the lug 17 and which may be brought against the arm 14 and then looked, thereby preventing any movement of the arm toward the lug 17 and, in consequence, preventing the closing of the vanes.

Stops 20 are preferably provided for the vanes 11 to engage the vanes when the same are in the initial or closed position. These stops are in the shape of ridges formed to one side of a plane passing through the axes of the vanes.

By providing passages for delivering air at right angles or normal to the plane of the register, and by providing means for varying the cross-sectional area of said passages, I can easily regulate the speed and direction of air flow without the use of velocity dampers in air ducts.

While I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and a plurality of revolving vanes, a pair of racks, means for coupling the alternate vanes to the same rack, and means for actuating said racks simultaneously whereby the alternate vanes are revolved in the same direction and the adjacent vanes in the oppositedirection.

3. In an air register, a plurality of vanes mounted to revolve, means for revolving the adjacent vanes in opposite directions and the alternate vanes in the same direction, and means for varying the amount of rotation of said vanes from the closing position.

l. In an air register of the class described, a plurality of vanes mounted to revolve, a

pinion associated with each of said vanes, a

pair of racks, each of said racks engaging alternate pinions, an arm for moving said racks simultaneously, and a slide adapted to be moved to and from the arm whereby the amount of rotation of the vanes may be varied substantially as and for the purpose set forth.

5. In an air register of the class described, a plurality of vanes mounted to revolve, a pinion associated with each of said vanes, a pair of racks, each rack engaging alternate pinions, an arm for moving said racks simultaneously in the same direction, and a slide on each side of said arm adapted to be moved into the path of the arm, whereby the movement of said arm and, therefore, the rotation of the vanes, may be restricted substantially as and for the purpose set forth.
